An additional of the drawings, the inking mechanism comprisesscrapenblade 2a is mountedon the edge of trough an ink fountain and aseries of transferring and 10 adjacent to blade '23 and contacts withthe 55 Cal fountain roll to remove all but a regulable thickness of inkfrom the fountain roll and thereby accurately control the supply of inkto the press. Blade 24 is provided with a plurality of adjusting screws25, threaded in the wall of trough 10 and bearing against the blade 24on its side away from roll 20. One such adjusting screw 25 is preferablyprovided for each column width of the plate cylinder so that the inkrequirements of each part of the press may be properly provided for.

For facilitating the silencing of any page width of the fountain, andthereby preventing the supply of ink to the corresponding portion of theplate cylinder, the trough 11 is divided into transverse sections bywebs 12 which project into grooves 27 formed in the surface of fountainroll 20. The scraping members 16 are movably mounted on shaft 17 and maybe secured in either scraping or non-scraping position by suitablemeans, such as set screws 28. In their lowered position, the members 16remove ink and feed it to the trough 11, whereas in their raisedposition (as shown in dotted lines in Figure 1) no ink is removed fromthe discs and consequently none is supplied to the corresponding sectionof trough 11.

As fountain roll 20 is slowly rotated, ductor roller 30 is periodicallyoscillated by any suitable means into contact with roll 20 andalternately into contact with the distributing roll 31 which is rotatedat a considerably higher peripheral speed than that of the fountainroller. Distributing roll 31 transfers its ink to distributing roll 32by means of transfer rollers 33 which are freely rotatable and heldagainst axial movement, while rolls 31 and 32 are vibrated in oppositedirections. Roll 32 runs in contact with form rollers 34 which contactwith and transfer ink to plates on the plate cylinder 35. All of rolls31, 32, rollers 33 and 34 and plate cylinder 35 run at substantially thesame peripheral speed, which is that of the web and impression cylinder36 while means are provided for driving the fountain discs 14 at anextremely low speed.

As shown in Figures 2 and 3 of the drawings, rolls 31, 32, cylinders 35and 36 and rollers 33 and 34 are mounted upon their respective shafts31, 32, 35, 36, 33' and 34', which are rotatably mounted in suitablebearings in press frames 21. Plate cylinder 35 is driven by means ofmitre gear 40 fixed on shaft 35 and in mesh with a mitre gear (notshown) driven from the main shaft. At its other end shaft 35 is providedwith a gear 41 meshing with a gear 42 fast on shaft 36' and having anequal number of teeth. Shaft 35 also carries a gear 44 meshing withidler 45 which drives gear 46 on shaft 32. Gear 47, on shaft 31' isdriven from gear 46 through idler 48. The gear ratio of gears 44, 46 and4'7 is such that the peripheral speeds of rolls 31, 32 and cylinder 35are the same.

A sprocket50 at the extreme end of plate cylinder shaft 35 drives acorresponding sprocket 51 on fountain roll shaft 22 through chain 52,and the drive ratio is such that the peripheral speed of the fountain isapproximately one-third that of the plate cylinder and distributingrolls. At one end of the fountain trough 1O fountain roll shaft 22 isprovided with a bevel gear 54 meshing with bevel pinion 55 on shaft 56and driving worm 57 in mesh with worm wheel 58 on the fountain discshaft 15, so that the fountain discs are driven very slowly relativelyto the fountain roll.

For vibrating the distributing rolls 31, 32, each of their shafts isprovided at one end with a ball bearing 60 held against axial movementby means of cap 61 and shoulder 62 and having its outer race seatedwithin collar 63. Collar 63 is pivotally connected with an eccentricyoke 64 by means of pivot pins 65. Eccentric yokes 64 are actuated bymeans of eccentrics 66 keyed to shaft 67 which is rotatably mounted injournal brackets 68 and driven through mitre gear 69 from shaft 22,thereby vibrating the distributing rolls 31, 32 at equal speeds inopposite directions.

Figures 5 and 6 of the drawings illustrate a modified embodiment of theinvention in which the ink is supplied to a small trough 11-from themain trough 10 by means of a motor or pressdriven, rotary, eccentricvane pump. As embodied, the motor or press-driven, rotary, eccentricvane pump 70 is connected to the lowermost portion of fountain trough10, on the intake side of the pump, by means of pipe '71, and thedischarge side of the pump is connected with header '72 by means of pipe'73. Connected with header '72 are a plurality of nozzles '74, one foreach transverse section of the smaller trough ll spaced along header '72and connected thereto by means of unions 75.

With the nozzles 74 extending perpendicularly to header '72, the ink isdelivered therefrom directly into the trough sections, but the nozzles"74 may be individually swung so as to return the ink to the main trough10 in case it is desired to silence any one or more individual pagewidths of the printing cylinder. Pump 70 is preferably capacitated todeliver ink at a rate slightly in excess of the maximum requirements ofthe press, thereby always maintaining a surplus of ink in the smallerfountain trough 11.
